Answer:
Yes ,we can prove the two triangles are similar by angle angle test.
Step-by-step explanation:
Given:
∠ABE = 45°
∠EAB = 63° and
∠MNP= 72°
∠NMP = 63°
To Prove:
ΔABE ~ ΔMPN
Proof:
In a Triangle sum of the angles of a triangle is 180°
In ΔMPN
∴ ∠MNP + ∠NMP + ∠MPN = 180°
Substituting the given values we get,
∠MPN = 45° ..........................( 1 )
Now,for triangles to be similar
- minimum two angles should be congruent i.e AA test.
- all the three sides should be proportional i.e SSS test
In Δ ABE and Δ MPN
∠ ABE ≅ ∠ MPN = 45° ……….{From ( 1 ) and Given}
∠ EAB ≅ ∠ NMP = 63° ………...{Given}
Δ ABE ~ Δ MPN ….{Angle-Angle test}
..........Proved

Answer:
What is it?
Two matrices can be added together if and only if they have the same dimension. Their sum is obtained by summing each element of one matrix to the corresponding element of the other matrix.
How is it used?
The numbers in a matrix can represent data, and they can also represent mathematical equations. In many time-sensitive engineering applications, multiplying matrices can give quick but good approximations of much more complicated calculations.
How can I solve it?
Here is a thing https://www.purplemath.com/modules/mtrxadd.htm
Step-by-step explanation:
Answer:
first thing to do is combine like terms
now you would have -x-4=4
this is because you added -6x+5x
now you would add 4 to each side
now you would have-x=8
then you would divide the negative because x has to be positive
now you would have x= -8
that is your answer. if you any questions just ask :D
